manner, a textile cover and a paddingV between the cover andseat bottoni usually being suiflcient, butin such instances, where tacks cannot be driven into the frame or seat bottom, considerable difficulty has been encountered in providing means for securing the covering in place at a reasonable labor cost and in a manner which Will be satisfactory in appearance.

*The objects of my invention are topprovide an improved construction whereby an all metal chair seat bottom may be provided with a rigid supporting means, and may be suitablyV covered `or upholstered Without difficulty and at smallexpense during the process of manufacture. v Y

It accomplish these objects by providing a construction in Which the means for attaching the chair legs to the seat bottom is comlbined with means for clamping the edge portion of the seat covering to the seat bottom vpermitting the entireV operation to be rapidlyperformed. n

. For a more complete understanding of the invention, reference is-made to t-he accom- .'pa'nying drawing, in whichf- Fig. l is a perspective vieuv of a chair em.- bodying my invention, partly broken away.

The particular construction ofchair shown is not-entirely essential to my invention, but

illustrates a. form in connection with whichl it is preferably employed and is Aespecially advantageous, all parts of the vchair shown aside from the upholstery, being made of metal. f

In the chair illustrated the back frame and Application med Jury 11, 1925. serial No. 42,937.

rear legs are formed of a continuous strip f of metal l of approximately U-shape, and

bent transversely into semi-tubular, and, at f some portions, a. nearly tubular form. The front legs 2 .are of similarly formed ymetal strips, the upper end portions being'shaped to conformto the inner surface of the corner portions of a nearly rigid,.or slightly fle-X- ible metal strip, or band 3, which is bent to conform to the approximately rectangular sha-pe of a sheet metal seat bottom Llathe corners of which are rounded.l `Said seat bottoni is lprovided with an edge flange 5, which is forinedby bending the edge portion thereof i,

downwardly at right angles,yand the edge portion of said flange-is inturned to form a lip 6, which extends at ,right angles to the flange, providing a recessor groove bet-Ween the under side of the seat bottom and thelip, and yinto which theband 3`is` adapted tobe tted and to` extend thereof. l

The front legsQ are vrigidlyl secured by rivets to the band 3, at'the inner sides lof the corners, vand are also connected to eachother bya front brace 7 and to the rear legsl by side bra-ces 8. A U-shaped back brace 9 is also preferably provided- Within the back frame 1.

A for 4 the entire Vlength In assembling the` portions ofthe chair l abo-ve referred to, a form X is provided having a recess therein, which corresponds to the shape of the seat bottom. The cloth covering l() for the seat, which Will have been cut` vto suitable shape, is laid over the recess, as

shovvn in Fig. 4, and suitable cushioning'inaterial l1 is placed therein, as shown in Fig. 5. The yseat bottom 4 is then placed in invertedl position on the materialV l1` and pressed' into the form, so as to draw the covering tightly over theseat bottom, and then the edge portions of thecovering'l() are f drawn over the flange 4;' and lip 5, so that it lies in the groove Within'the lip 6, as shown .in Fig. 6, in which position it inav `be tempoly collapsed by springing its end portions out of line and pressing its side portions towards each other, so that said end portions overlap t an extent, and then the front portion thereof is inserted in the front portion of the recess between the seat bottom and the lip 6 and then it is pressed downward until it is level and may be sprung into the recess thruout its entire length with its ends in abutment. The band 3 is so formed that, when in this position, its sides will be pressed against the bottom of the recess in the seat bottom with sufficient force to clamp the edge portion of the covering 1() firmly against the bottom of the recess.

The drawing action on the covering caused i by the action of forcing the seat bottom into the form, and the action of the band 3 in forcing the covering into the recess of the Seat bottom, will ordinarily be sufficient to take up all slack material and pull out all wrinkles in the covering. In case, however, it should be found that the covering is not drawn over the seat bottom as tightly as is desired, suliicient material may be provided to extend beyond the edge of the clamping band, so that, by pulling thereon, all wrinkles may be pulled out, and if the band is found t0 clamp the covering too firmly to permit this to be done, its clamping effect may be relieved by pressing the abutting ends out of line and springing the sides toward each other. The covering may then be drawn as tightly as desired and reclamped by springing the band back into position as shown in Fig. 8. The clamping action of the band will then be increased bythe attachment of the back and rear legs l and back brace 9, clamping bolts 14 being passed thru the legs 1, the side portions of the flange 5, near the back edge of the seat bottom, and thru the covering and the side portions of the band 3, and, by means of nuts on the inner ends of the bolts 14, the side portions of the band will be firmly clamped against the covering in the seat bottom recess, as shown in Fig. 9. If any additional clamping action is secured beyond that secured by the resiliency of the band or the action of pulling its ends into abutment, the abutting ends will be slightly separated, the construction permitting as strong a clamping action to be secured as may be desired, and at the same time the rear legs will be secured to the seat bottom and to the band 3. The legs will also be secured to the rear end of the braces 8, if this has not been d one previously. The brace portion 9 will then be secured to the back flange portion of the seat bottom, in a similar manner, bolts 15 being passed thru the same and thru the flange and end portions of band 3, so that, when the clamping nuts are tightened thereon, the end portions of the band will be clamped firmly against the covering, as shown in Fig. 9.

As shown, the middle portion of the brace 9 is secured to the middle portion of the frame 1, and the end portions of thebrace 9 are extended beneath the scat and connected to the leg portions of the frame 1. As thus arranged all parts of the chair will be firmly secured together and the upholstery securely attached to the seat bottom. y

If it is desired to renew the upholstery7 this may be readily accomplished by removing the bolts 14 and 15, so as to release the band 3, these bolts being made detachable for this pur ose. Y

I hile the above described construction is primarily designed for use in connection with a chair, it may beemployed to advantage in holding a covering in position on a table top, which use is deemed to be equivalent to the use herein claimed.

In addition to the advantages secured by reason of the facility with which the seat covering is drawn into position and the eifectiveness with which it is secured, by means of the above described construction, the means provided for secure attachment of the legs is particularly advantageous, as the additional rigidity secured by providing the relatively heavy metal strip 3, to reinforce the comparatively thin flange on the edge of the seat bottom, is of great importance, andat the same time a means for attaching the front legs is provided which is not visible from the front.

I claim- 1. In a chair, a seat comprising a sheet metal plate having a depending edge flange extending about the same, a seat covering eX- tending over the upper surface thereof and about said flange onto its inner side, a metal clamping strip arranged beneath said plate and having means to clamp the same against the inner side oflsaid ange, to clamp said covering between said flange and strip, and supporting legs having means for securing the same to said clamping strip. y

2. In a chair, a seat comprising a sheet metal botom plate having a depending flange extending about the edge thereof, said flange having an inturned lip at its edge forming a recess between said lip and the under side of the plate, a covering extending over said plate and about said flange and into said recess, a exible metal strip closely tted in said recess and extending thruout thelength thereof, means to clamp said strip against the bottom of said recess to secure the same to the plate and to clamp the covering thereto and supporting legs for said seat attached to said strip.

3. In a chair, a sheet metal seat bottom having a depending edge flange extending continuously about the entire edge thereof and determining the contour of the seat, said flange having an inturned lip at its lower Y edge forming a recess between the same and the under side of the seat bottom a semi rigid metal strip fitted in said recess and extending thruout the length thereof, with its ends in abutment, at the rear of the seat, a covering extending over said seat bottom and about removable means engaging oppositeend por-y tions of' the strip to clamp the strip and legs to the adjacent portions of said flange.

4. In a chair, a sheet metal seat plate having a depending edge flange extending continuously about the entire edge thereof and havforming an internal recess, a seat covering extending over said plate and about said flange into said recess, a transverselyrigid metal strip adapted to be sprunginto said recess, so that it ends abut, and arranged to fit closely within the recess and clamp the ing an inwardly projecting lip at its lower endy edgev portion of' the covering against the bottomthereof and legs for the chair rigidly attached to said strip.

5. In a chair, a. sheetfinetal seat plate having a` vertically depending llange extending about the entire edge thereof, said flange having alip at its lower edge projecting right angularly inward therefrom, and'upholstery covering extending over the plate and flange and about said lip onto the inner side of the flange', a relativelyrigid metal strip extending for the length of the flange and arranged to fit closely between said lipand the under side of the plate and to clamp the covering against the lip and the inner side of the -flange, and legs secured to the inner side of said strip.
